Plutonium Age Dating for Nuclear Forensics: A Close-up on the Pu/U Chronometers

摘要

A 'roadmap' for dating of plutonium via all four Pu/U clocks has been established that allows the radiogenic and non-radiogenic uranium in plutonium samples to be distinguished, but also gives clues on the nature of non-radiogenic uranium traces. The project on plutonium CRMs certified for their separation date is progressing and will supply the nuclear forensics, safeguards and security communities with the needed CRMs in the foreseeable future.
